Re: [Exist-open] BNF / EBNF / ABNF / ANTLR handling

[Alexander H. <ah...@xs...>]

I guess that is what I want yes. I've seen how to load a syntax in Java, generate a parser and then request to validate a given string and finally return the parsed tree. 

No idea where to start in exist-db. I believe there's ANTLR somewhere but can you reach that with pure xquery or does require calling Java from xquery?
